My car is out of warranty and the ticking isn't that bad. But I was wondering if I don't do anything about it will it damage anything in the engine?

I recall in the thread where someone indicated scored parts. I regret now when the dealer replaced the lifters that I did not ask to see it in person. Hopeful someone going forward may ask, and get some recent images after many miles were put on the N52. Not sure how well that would go over at the dealership though....
